Matrix visual column width problem started April 25-26th

I am experiencing exactly the same issue and can fully confirm this is not an isolated case.

In my scenario, multiple reports in Microsoft Power BI were working correctly before, and suddenly (within hours) started showing this behavior in Power BI Service.

Key points from my side:

• Reports were working correctly before (same as described, prior to April 25–26).

• No changes were made to the reports or visuals.

• The issue appeared suddenly and is affecting multiple reports.

• Matrix visuals in Power BI Desktop display correctly.

• After publishing, in Power BI Service:

  • Column widths are not respecting manual adjustments.

  • Even with Auto-size column width turned OFF, columns expand automatically.

  • Long text fields force the column to stretch far to the right.

  • Layout becomes unusable, requiring excessive horizontal scrolling or making data inaccessible.

• This behavior is also reproducible across different reports and environments.

Additionally, I have observed:

• Attempting to manually resize columns does not persist.

• Columns “snap back” or expand again based on the longest value.

• Even with Word Wrap enabled, the issue persists.

• Workarounds like collapsing rows only partially mitigate the issue and are not viable solutions.

This strongly suggests a recent regression or change in how matrix visuals are rendered in Power BI Service.

This is a critical issue because:

• It breaks report layouts that were previously stable.

• It affects usability and readability for end users.

• It impacts multiple reports at once without any changes on our side.

Could the team please investigate this with high priority?
Given that multiple users are reporting the same behavior starting at the same time window, this appears to be a service-side issue rather than a configuration problem.

Thank you.
